Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dread when you notice something isn’t quite right with your furnace. You’re sitting at home and you hear your furnace is constantly kicking in and shutting off. However, before you panic, there are several items you can check when you realize your furnace seems to be shutting off a lot more than it should be.

  1. Check the air filter in your furnace—You may think that air filters are only used to help keep the air in your house cleaner, but they also help keep your system clean. Your first step when you realize there is a problem with your system should be taking a look at your air filter to see if it needs to be replaced. If it’s clogged or dirty, it can make it tough for air to flow over the heat exchanger.
  2. Look at your thermostat—For many of us, we may have set our thermostats weeks ago and forgot about it, particularly when using a smart or programmable thermostat. Look at your thermostat to see if anything strange is occurring or if it may need new batteries. The location of your thermostat could make a difference, as well. If it’s located in a place that’s often hotter than the rest of your home, such as in direct sunlight or near another heat source, it could be mistakenly assuming your home is already up to the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have appropriate insulation, your furnace is likely to shut off more regularly. Walk around your home and check the windows to ensure they are all closed and examine the seals around your windows for any drafts or cold air entering the home.

While you can certainly check for some of these issues on your own, if issues still continue after these checks, it might be time to call in the experts. When your furnace is always turning off, it can lead to unnecessary work and stress on your system that could cause more expensive repairs or even a replacement.
